Ultrashort laser technology involves the generation of extremely short pulses of laser light, typically in the femtosecond (10^-15 seconds) or picosecond (10^-12 seconds) range. This technology allows for precise and high-resolution laser processing, such as micromachining, surface structuring, and material analysis. Ultrashort lasers are also used in a variety of scientific and medical applications, including multiphoton microscopy, medical surgery, and laser eye surgery. The ultrafast nature of these lasers enables researchers to study rapid processes in physics, chemistry, and biology with unprecedented temporal resolution. Overall, ultrashort laser technology has revolutionized various fields and continues to make significant advancements in research and applications.
